Oracle Database 12c Backup and Recovery Survival Guide

Overview of this book

The three main responsibilities of a successful DBA are to ensure the availability, recoverability, and performance of any database. To ensure the recoverability of any database, a DBA needs to have a strong backup and recovery skills set. Every DBA is always looking for a reference book that will help them to solve any possible backup and recovery situation that they can come across in their professional life. Oracle Database 12c Backup and Recovery Survival Guide has the unique advantage to be a reference to all Oracle backup and recovery options available, making it essential for any DBA in the world. If you are new to Oracle Database, this book will introduce you to the fantastic world of backup and recovery that is vital to your success. If you are an experienced DBA, this book will become a reference guide and will also help you to learn some possible new skills, or give you some new ideas you were never aware about. It will also help you to easily find the solution to some of the most well known problems you could find during your career as a DBA. This book contains useful screenshots, scripts, and examples that you will find more than useful. Most of the books currently available in the market concentrate only on the RMAN utility to backup and recovery.

It covers the most important topics on Oracle database such as backup strategies, Nologging operations, new features in 12c, user managed backups and recoveries, RMAN (including reporting, catalog management, troubleshooting, and performance tuning), advanced data pump, Oracle Enterprise Manager 12c and SQL Developer.

New concepts with Data Pump


Some new concepts were introduced with Data Pump when comparing it with the original export and import utilities; they are:

  • Directory objects: In order to use Data Pump, the DBA must create a directory object that defines the location where it will create or locate the dump, log, or SQL files during an import or export operation, and grant privileges to the user on that directory object (such as READ and WRITE). If a directory object is not specified, a default directory object called DATA_PUMP_DIR is provided. This default DATA_PUMP_DIR is available only to privileged users unless access is granted by the DBA.

  • Interactive command-line mode: This mode allows you to take full control of all Data Pump jobs running in the database. You can easily monitor and manage the jobs running, and do things such as stop, re-start, or kill a job. This also gives you the ability to detach from a running job and later reconnect to it, if necessary.
